Identification of slide coagulase positive, tube coagulase negative Staphylococcus aureus by 16S ribosomal RNA gene sequencing.
AIMS To ascertain the clinical importance of a strain of slide coagulase positive but tube coagulase negative Staphylococcus species isolated from the blood culture of a 43 year old patient with refractory anaemia with excessive blasts in transformation who had neutropenic fever. METHODS The isolate was investigated phenotypically by standard biochemical methods using conventional biochemical...
متن کاملBiotyping coagulase-negative staphylococci.
The biochemical profiles obtained with Staph-Ident (Analytab Products, Plainview, N.Y.) panels were combined with the results of adherence and synergistic hemolysis tests to define biotypes among 1,064 clinical isolates representing eight species of coagulase-negative staphylococci. The 672 isolates of Staphylococcus epidermidis were aligned in 69 of 144 potential biotypes in our scheme because...
متن کاملCoagulase-negative staphylococci.
The definition of the heterogeneous group of coagulase-negative staphylococci (CoNS) is still based on diagnostic procedures that fulfill the clinical need to differentiate between Staphylococcus aureus and those staphylococci classified historically as being less or nonpathogenic. Due to patient- and procedure-related changes, CoNS now represent one of the major nosocomial pathogens, with S. e...
متن کاملPurification of staphylococcal coagulase.
Correlation between the pathogenicity of certain staphylococci and their ability to produce coagulase has led to extensive studies of the clotting enzyme. Walston (1935) precipitated the clotting substance from cell-free filtrates of appropriate staphylococcal cultures by the use of ethanol, acetic acid, or ammonium sulfate. Walker et al. (1948) partially purified staphylocoagulase by repeated ...
متن کاملFibrinogen and the slide coagulase test.
The advantages of using solutions of fibrinogen instead of plasma for carrying out the slide coagulase test were pointed out by Berger (1943) when he showed that their use avoided false positives due to naturally occurring staphylococcal agglutinins in rabbit and human plasma, in addition to the fact that these solutions retained their activity considerably longer. Using fibrinogen he demonstra...
